The basic rule associated with the design of asynchronous circuits, either in
hardware or software, where you are thinking about waiting some specified
time for a process to complete, but have no assurance otherwise that it has,
is: "Never do it. Never implement an asynchronous circuit. Always find some
way to make the circuit synchronous (i.e., handshake)."

Something like trigger files are going to be the only reliable way to make
this work.
